Answer:
Improved agricultural practices have led to increased productivity, decreased organic production, increased health risks, increased water pollution, and increased profits.
Explanation:
Since the turn of the 20th century, agriculture has experienced numerous changes and is much different nowadays than it used to be. This has been due to rapid technological development, which has also improved agricultural practices. The improvements have been in every sphere, from the protection of the plants to create more resistant and plants that have higher productivity, better irrigation, mechanization, bioengineering, and at the end of it all it has led to higher profits.
The developments in genetics have led to the creation of plants that are more resistant to diseases and have higher productivity. The pesticides, herbicides, and fungicides have all helped in the protection of the pants and destruction of pests, which further led to an increase in production, but their usage has also led to pollution of the soil and water. Unfortunately, the usage of chamicals has led to increased health risks, and significantly lowering the organic production which was dominating before.
The answer is B. climate is the general weather pattern of an area over many years.
This process is known as c>folding.
The occurrence of folding happens when crustal plates move together under the compressional force, causing the rocks to fold into a series of waves. In some cases folding might be small scaled and not significant, while in large scaled folding features like the fold mountains will be formed.
Let's look into the rest of the answer one by one:
a>deposition
Deposition is a movement that occurs under gravity, where the small particles of rock or soil is deposited on the surface. It could occur when the current of water is gentle, or when rock weathers and the smaller particles fall off. A long term deposition could cause the formation of sedimentary rock when particles accumulate.
b> faulting
Faulting can occur under compressional force, shear force or tensional force. When the compressional force is so strong that overthrust occur, the rock might break under the pressure and cause faulting. While shear stress and tensional force will pull the rock apart and cause faulting. Some examples caused by faulting is rift valley.
d> weathering
Weathering is the break down or dissolving of rock under physical factors or chemical factors. For example, under the difference of temperature, the rock will contract and expand at an alternate rate and break apart. An example for chemical factors is when the rock that include dissolvable materials dissolved under acid or water.
Therefore the answer is c>folding.
Hope it helps!
Answer:
Correct answer is: "If a planet's rotational axis has no tilt with respect to its orbital plane, then it has no seasons".
Explanation:
Hello!
We call stations a period of time characterized by a particular behavior of the meteorological parameters. On earth, the seasons are 4 and last 3 months.
The stations are produced by the inclination of the planetary axis of rotation with respect to the plane of translation, with which they move around the sun. The axis of terrestrial rotation is inclined approximately 23.45 ° with respect to the plane of the orbit with which it surrounds the sun.
